Getting at the Quark Mass Matrices
نویسندگان
چکیده
We present a class of Ansätze for the up and down quark mass matrices which leads approximately to: |Vus| ∼ √ md/ms, |Vcb| ∼ ms/mb, and |Vub/Vcb| ∼ √ mu/mc. Sizes of the Kobayashi-Maskawa matrix elements are controlled solely by quark mass ratios. In particular, we introduce no other small parameter and our results do not rely on delicate cancellation.

A QUARTIC POTENTIAL FOR THE NUCLEONIC QUARKS
We assume that each valence quark in a nucleon is in a phenomenological modified harmonic oscillator potential of the form: ( l+yo) (ar +br+cr +dr ), where a, b, c and d are constants and ? is one of the Dirac matrices. Then by making use of a suitable ansatz, the Dirac equation has a very simple solution which is exact. We then have calculated the static properties of the nucleon in the ...
متن کاملBounds on quark mass matrices elements due to measured properties of the mixing matrix and present values of the quark masses
Abstract We obtain constraints on possible structures of mass matrices in the quark sector by using as experimental restrictions the determined values of the quark masses at the MZ energy scale, the magnitudes of the quark mixing matrix elements Vud, Vus, Vcd, and Vcs, and the Jarlskog invariant J(V ). Different cases of specific mass matrices are examined in detail. The quality of the fits for...
متن کاملFour-Zero Texture of Hermitian Quark Mass Matrices and Current Experimental Tests
We show that the four-zero texture of Hermitian quark mass matrices can survive current experimental tests: it is able to yield sufficiently large predictions for the flavor mixing parameter |Vub/Vcb| and the CP-violating parameter sin 2β, without fine-tuning of the input values of quark masses, provided the (2,2), (2,3) and (3,3) elements of up and down mass matrices roughly satisfy a geometri...
متن کاملGeneral determination of phases in quark mass matrices.
We construct new invariants and give several theorems which determine in general (i) the number of physically meaningful phases in quark mass matrices and (ii) which elements of these matrices can be rendered real by rephasings. We illustrate our results with simple models. email: [email protected] email: [email protected] Understanding fermion masses and quark mixing rem...
